Thanks for the clarification. So the 4k minimum was due to fiber's stack.

I was just wondering why nginx could use less than a single page,

it might be using a different approach, which I have no idea of.

Nginx doesn't use fibers. I believe it just uses callbacks like node.
These can use much less memory than callbacks at the expensive of being
annoying to program.
